Overview

Amazon has introduced “recommended product groups” within its Ships in Product Packaging (SIPP) program, allowing sellers to certify an entire family of variations with a single test instead of filing separate reports for each ASIN. The change, announced in early 2024, targets lines that differ only by color, scent, flavor, or minor size adjustments, and it can reduce both certification time and costs for eligible sellers.

Key Points

• Single‑test certification — Sellers can obtain SIPP approval for all items in a group by testing only the largest and heaviest variant, cutting the number of required lab reports by up to 90 % for ten‑color lines.
• Group definition criteria — Amazon clusters products that share the same packaging dimensions, weight range, and material composition, even if they differ in non‑structural attributes such as flavor or hue.
• Primary product rule — The heaviest SKU in each cluster is designated the “primary product”; its successful test automatically extends certification to every secondary SKU in the same group.
• Liquid exception — Items containing liquids must still undergo individual testing because leakage risk is not mitigated by size or weight similarity.
• Fragile‑item exception — Products classified as fragile (e.g., glass, ceramics) are excluded from group testing, requiring separate certification for each variation.
• Catalog‑wide visibility — Sellers can view their automatically generated groups in the SIPP enrollment page of Seller Central, where a downloadable CSV lists primary SKUs, grouped ASINs, and current certification status.
• Time savings — For a catalog of 500 eligible SKUs, the new process can eliminate up to 450 individual test submissions, potentially shaving weeks off the overall enrollment timeline.
• Fee reduction impact – Once certified, each unit ships in its own branded box, eliminating the need for Amazon’s overbox and lowering dimensional‑weight fees by an average of 12 % per unit for standard‑size items.
• Sustainability boost – Certified products qualify for Amazon’s “Sustainable Packaging” badge, which has been shown in internal studies to increase conversion rates by roughly 3 % on comparable listings.
